  • !
    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: a1-101.akam.net: "41824.8"; a1-101.akam.net: "41824.9"; a10-65.akam.net: "48878.30"; a10-65.akam.net: "48878.29"; a13-64.akam.net: "41824.4"; a14-64.akam.net: "48878.30"; a14-64.akam.net: "48878.32"; a4-66.akam.net: "48878.30"; a4-66.akam.net: "48878.31"; a7-65.akam.net: "41824.4"; a7-65.akam.net: "41824.11". Hide or replace the version string.

    Very low TTLs
    Records · These records have a TTL below 5m, causing extra queries and slower lookups: A (20s), AAAA (20s). Low TTLs are useful just before a planned change. The NS TTL at the parent is 1h and in the zone 1d; resolvers may use either.

Problems

  • ✗
    No DMARC record
    DMARC · No DMARC record was found for this domain. DMARC is essential for preventing email spoofing. Add a DMARC record with p=reject or at least p=quarantine.

    Signatures expire in 53h0m0s
    DNSSEC · DNSKEY signatures expire at 2026-10-24T20:20:50Z (in 53h0m0s). Check that re-signing works.
    #21
  • !
    1024-bit DKIM key
    DKIM · 1024-bit RSA keys are the minimum and are considered weak today: dkim (1024 bits). Rotate to a 2048-bit key.
    #23
  • !
    Not configured
    TLS · MTA-STS is not configured, so other mail servers fall back to unencrypted delivery when TLS fails or is stripped by an attacker. Publish a _mta-sts TXT record and a policy at https://mta-sts.<domain>/.well-known/mta-sts.txt.
